SAFETY TOOL CHECK.

Application led July 1926. Serial No. 120,686.

In withdrawing tools from a well, particularly cable tools, the controlhead or the like at the top of hit; causing the tool to break oil of thecable l and fall back into the well; causing serious damage. 4

An object of my invention is to provide -novel cheek for the well toolsto prevent their accidentally falling into the well.

Another object is to provide a simple and effective tool check whichwill automatically act to catch the tool if said tool is accidentallydropped into the well.

Other objects, advantages and features l of invention may appear fromthe accompanying drawing, the subjoined detailed description, and theappended claims.

In the drawing, Fi 1 is a longitudinal sectional view of l0 my c eek inposition in a casin Fig. 2 is a sectional view ta en on line 2--2 Fig.1.

Fig. 3, is a sectional view taken on line 3-3 Fig. 1.

Referring more particularly to the drawing; a pipe section 1,approximately the same diameter as the casin 2, is secured to the casinand is positione below a control head or t e like 3 mounted on pipesections 4 secured to the upper end of said pipe.

In the pipe section 1 is pivotally mounted a plate 5. which normallyrests across said pipe to close the same. A ledge 6 is provided in theipe upon which the plate 5 rests. A rod extends through, and is securedin the plate 5 and said rod is'journaled in the walls of the rod is bentdownwardly and a weight 8 is sethe easing, is frequently p pipe 1. Oneend of the cured thereto, whereby the plate 5 is always earreld to aclosed position resting across the A slot 9 is formed in the plate 5through which the cable, drill stem or the like extends. The slot is notwide enough to permit passage of the bit` 10, but the bit strikes theplate; swinging it upwardly to permit its passage, after which theweight 8 ycloses the plate and if the bit should fall it would strikeand rest on said plate.

A recess 11 is provided in the pipe section 50 1 to accommodate theplate 5 when it is swung upwardly; thus leaving a free passage for thetools or the like,

When it is desired to lower tools into the well, the weight 8 may begraspedand the 55 plate 5 swung to open position, leaving the passageclear.

Having described my invention I claim- 1. A tool check adapted to bepositioned vin a well easing, comprising a plate normal- 00 ly restingacross the casing, said plate having a slot therein to permlt passage ofthe drilling stern or the llke, a rod upon which said plate is mountedand a weight depending from said rod whereby the plate is urged vto aposition across the casing.

Y 2. A tool check comprising a pipe section adapted to be positioned inthe casing, a plate having a slot therein through which the drill stemor the like extends, a ledge adapted to sup ort said plate when inclosed position, a ro secured in the plate, and a weight depending fromsaid rod whereby the plate is normally urged to closed position.

In testimony whereof I aflix my si nature.

GUSTAVE J. COR IER.
